UNITED STATES PATENT OEETCEC DAVID EMONNOT, OF NEW YORK, N. Y.

NUMBERlNG-STAMP.

Speciiication forming part of Letters Patent N0. 55,078, dated May ,29, 1366.

To all whom it may concern:

Be it known that l, DAVID EMONNOT, of the city, county, and State of New York, have invented a new and useful machine combining the advantages of a seal and a luechanical composing-stick for the stamping and numbering ot' any notes, papers, documents, or articles in trade, Sac., which I wish to be called Emonnots Mechanical Compositor and Seal 5 and I do hereby declare that the following is a full and exact description of the construction and operation of the said machine, reference being' had tothe annexed drawings, making a part of this specification, and on which- Figure A represents a side view; Fig. B, a

` longitudinal front view or elevation; Fig. C,

a view of thc seal-plate and numbers or iigures to be printed. Figs. D, E, F, and G are sections showing` the divers important parts or pieces of the mechanism of said compositor, which said parts are specitied and distinguished on the figures of said drawings by Nos. 1, 2, 3, Sto.

No. 1, case or frame containing mechanism 5 No. 2, counter-case 5 No. 3, base-plate, on which restthe rods, mainspring, and the handle5 No. 4, seal-plate, which may he constructed in any shape or formjto suit the purposes, wants, and fancies of the user, and on which plate any name, figure, notation, emblem, &c., can be engraved; No. 5, shaft of the machinery5 No.6, type-wheels, on the edge of which any characters, letters, iigures, days of the week, months, years, Src., can be engraved or adapted at will, the number or" said type-wheels varying according to the number ofiigures to be printed at once with the said compositor. (Four typewheels are shown in the drawings accompanying this specication.) No. 7, coupling-wheels adapted to the type-wheels to help revolving and keep types iirm in their position; No. 3, bolts with spiral springs so adapted to or fixed in each type-wheel as to operate or communicate the revolution from the ratchet No. 9 to the divers type-wheels at proper time; No. 9, clink or ratchet-wheel, by means of which the machinery is set into motion 5 No. 10, springs of the crankwheels setting and retainin gthe types in proper position5 No. l1, mainspring resting on the base-plate No. 3, ending with a hook, which advances one degree on the clink and catches one cog farther at every stroke of the working-rod, and brings the same one division round when the trigger 13 is worked; No.11/,counter-spring of the ratchet 9 to keep it in position 5 No. 12, spiral spring ofthe workin g-rod, bringing that rod and base-plate back to their original position, and by mean s of th e mainsprin g setting the machinery into motion 5 No. 13, trigger with hook to retain the machinery at rest5 No. 13 spring ofthe trigger; No, 14, bridge or support ot' the trigger 5-No. 15, woikiiig-1'otliixed inthe counter-case, base-plate, and screwed to the handle; No.16,handle5 No.17, small rod tixed in the base-plate and working the bolts at the end of each series of igures5 No. 1S, holes or notches in the coupling-wheels 7 to receive the Vbolts and communicate or transmit motion to the next type-wheel, No. 65 No. 19, guidingrod to keep the machine straight and rm.

Operation: A pressure or stroke on the handle when the sealis applied to any object will set the working-rod No. l5 in motion and act on the base-plate No. 3, on which rest the mainspring No. l1, the trigger No. 13, andthe small rod No. 17, so that these pieces will move at the same time, the mainspring No. 11 will catch the next cog of the ratchet No. 9, the hook of the trigger No. 13 catch the counter-caseNo. 2, and thereby retain the machinery in position until the trigger No. 13 be worked5 then the working-rod, base-plate, and mainspring are brought to their original position. The mainspring at the same time works the ratchet and first type wheel No. 6 one degree and changes one figure on the seal, and so ou at every stroke to and fro of the handle and working-rod until the first series of figures be through. XVhen the first series is over, or when the rst type-wheel has perfected one revolution, the small rod No. 17 comes in contact with the boltof the ratchet No. 9 and first type-wheel No. 6 so as to bring the back end of that bolt into one of the holes (N018, Fig. D) ofthe coupling-wheel No. 7, attached to the next type-wheel, 6, which revolves one degree also. Then the small rod will, next stroke, pass over the head of the irst bolt, (No. S in Fig. F and G,) so as to let go the connection of the two type-wheels. By a repetition of the same operation as described so far the second series will be worked through, and at the end of that has perfected one revolution, the'rst bolt will ters Patent, s-
